Fr33zypop Posted July 8, 2022 Report Share Posted July 8, 2022 I knew this would eventually happen as I have been the most gentle with these carbs but last night was the last straw. The threads for the screws for the bowl cover let loose and I wanted to see what options I have are. I am familiar with tapping new threads. The only threads I lost are the one with the little round guides to hold the fuel overflow tubes. I tried and was able to get them tight without those guides so I am wondering it I should look for longer screw? I've only tapped steel so with aluminum I just want to be sure I don't mess it up more. The last option I have is to get a new pair of 28 keihin and seems like my best option. These old carbs have seen better days.. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted July 8, 2022 Report Share Posted July 8, 2022 Depends.. Are you ever going to build a motor or stick with this one? Quote Link to comment Share on other sites More sharing options...
Fr33zypop Posted July 9, 2022 Author Report Share Posted July 9, 2022 The current setup meets my needs so probably nothing crazy. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted July 9, 2022 Report Share Posted July 9, 2022 I’d probably just go 28mm PWK then. Quote Link to comment Share on other sites More sharing options...

caleb90 Posted July 10, 2022 Report Share Posted July 10, 2022 Try a longer screw, run a tap in to clean the hole up. Just use lots of oil and go slow, aluminum will plug and bind the tap if you go to fast Quote Link to comment Share on other sites More sharing options...
caleb90 Posted July 10, 2022 Report Share Posted July 10, 2022 Loctight also makes a thread repair epoxy, ive used it and it does work. Just some options before you buy new Quote Link to comment Share on other sites More sharing options...
diebog Posted July 11, 2022 Report Share Posted July 11, 2022 If there is room you can also get a helicoil kit. Amazon or eBay. There are the China brands as well for allot cheaper. Then the threads would be steel and would hold up for the life of the carb Quote Link to comment Share on other sites More sharing options...
